This version of TiMidity should contain all the fixes from the
|
|
September 25 2003 SDL_mixer CVS snapshot, plus extended GUS patch
|
|
support from later SDL_mixer. In addition, it contains these changes
|
|
from SDL_sound:
|
|
|
|
* Removal of much unused or unnecessary code, such as
|
|
|
|
+ The "hooks" for putting a user interface onto TiMidity.
|
|
+ The antialias filter. It wasn't active, and even at 4 kHz I
|
|
couldn't hear any difference when activating it.
|
|
+ Removed all traces of LOOKUP_HACK and LOOKUP_INTERPOLATION.
|
|
According to the code comments they weren't very good anyway.
|
|
("degrades sound quality noticeably"). I also removed the
|
|
disclaimer about the "8-bit uLaw to 16-bit PCM and the 13-bit-PCM
|
|
to 8-bit uLaw tables" disclaimer, since I believe those were the
|
|
tables I removed.
|
|
+ Removed LOOKUP_SINE since it was already commented out. I think we
|
|
can count on our target audience having math co-processors
|
|
nowadays.
|
|
+ Removed USE_LDEXP since it wasn't being used and "it doesn't make
|
|
much of a difference either way".
|
|
+ Removed decompress hack from open_file() since it didn't look very
|
|
portable.
|
|
+ Removed heaps of unnecessary constants.
|
|
+ Removed unused functions.
|
|
+ Assume that LINEAR_INTERPOLATION is always used, so remove all
|
|
code dealing with it not being so. It's not that I think the
|
|
difference in audio quality is that great, but since it wouldn't
|
|
compile without code changes I assume no one's used it for quite
|
|
some time...
|
|
+ Assume PRECALC_LOOPS is always defined. Judging by the comments it
|
|
may not make much of a difference either way, so why maintain two
|
|
versions of the same code?
|
|
|
|
* Made TiMidity look for its configuration file in both /etc and
|
|
/usr/local/lib/timidity. (Windows version remains unchanged.)
|
|
|
|
* The following files have been removed: controls.c, controls.h,
|
|
filter.c, filter.h, sdl_a.c, sdl_c.c
|
|
|
|
* Added support for loading DLS format instruments:
|
|
Timidity_LoadDLS(), Timidity_FreeDLS(), Timidity_LoadDLSSong()
|
|
|
|
This version of TiMidity also contains my own changes for ZDoom:
|
|
|
|
* Removed readmidi.c: TiMidity is now fed MIDI events directly to
|
|
produce output. The TimidityMIDIDevice class is responsible for
|
|
feeding TiMidity data and collecting output from it. Since
|
|
ZDoom's MIDI parser ignores SysEx messages, so does this TiMidity,
|
|
though this can be changed if necessary.
|
|
|
|
* Removed all the precalculated math from tables.c in favor of using
|
|
real math functions.
|
|
|
|
* All sample values are now floats, and only a stereo 32-bit float
|
|
output buffer is supported.
|
|
|
|
* Moved everything into the Timidity namespace.
